There is no one in this world that is irreplaceable, and there is nothing that one must have. It has been more than twenty years, and your yearning for her has not diminished. It only means that you have overly admired the beauty of love and exaggerated the sadness of lovelorn. If you love her, hide her deep in your heart that no one can touch at any time, and bless her silently!
Concept: Love is always childish, and true love is often fruitless.
